Magnetic Measurement

DiskMapper H7 System - MicroSense, LLC (MicroSense, LLC)

The DiskMapper H7 system quickly determines the uniformity of the perpendicular recording layer of Heat Assisted Magnetic Recording (HAMR), also called Thermally Assisted Recording (TAR) disks, immediately after deposition, an important factor in the yield of disk drives. Utilizing a custom 7 Tesla bi-polar high speed superconducting magnet, the hysteresis loop of any disk location can be measured in less than 3 minutes.
